WINDOW CONSTRUCTION.

Patented Jan. 17, 1922.

Application filed December 6, 1920. Serial No. 428,643.

To all whom it may concern:

Be it known that I, STANLEY V. NIoHoL- soN, a citizen of the UnitedStates of Amen ica, residing at Toledo, in the county of Lucas and Stateof Ohio, have invented certain new and useful Improvements in WindowConstruction, of which'the following is a specification, referencebeing-had therein to the accompanying drawings.

'This invention relates to window constrpctions and more particularly towindow constructions employing a vertically slidable window member.

It is the object of the invention to provide an improved weather seal atthe top of a chamber which receives a vertically slidable window memberin its opened lowered position.

A preferred embodiment of the invention is hereinafter described andillustrated in the accompanying drawing wherein;

Figure l is a fragmentary exterior front view of a window constructionequipped with the improved weather sealing means;

Figure 2 is a vertical cross .section of the same.

In these views the reference character A designates a window frame inwhich the glass plate or window member B is vertically .slid'able, saidplate being adapted in its lowered opened position to enter the chamberC underlying said frame. The bottom edge of the plate B is embraced by achannel forming strip D, the upper edge portion of which is flangedoutwardly from the exterior face of the plate. B as indicated at E toprovide a seat for a weather strip F for med preferably of rubber. Whenthe glass plate,

B is in its closed raised position indicated in thexdrawings, theweather sealing strip F abuts against a complementary sheet metalweather sealing strip Gr extending the full width of thewindow openinflanged inwardly at its upper edge as indicated at G so as to form astop against which the sealing strip F is compressed in the uppermostlimiting position ofthe plate B. A clearance is provided between theflange G and the plate Band the strip F is flanged upwardly from end toend as indicated at H to providea closure for said clearance space.

A very positive seal against water enterany pocket wherein water maylodge to be discharged into the chamber C when the sliding plate islowered.

What I claim as my invention is:

1. In a window construction, the combination with a vertically slidablelass plate, of a resilient weather strip extended across and directlyengaging said glass plate adjacent its lower end and flanged upwardly inproximity to the glass. plate, a complementary stationary weathersealing member engageable by said resilient strip in the raised positionof the glass plate and having a clearance from the glass plate closed bythe flange of said resilient strip in the raised position of the glassplate.

2. In a window construction, the combination with'a vertically slidablewindow member, of a sheet metal channel member embracing the lower edgeof said window member, a weather strip carried by the upper portion ofsaid channel member and extending across'the window member, and acomplementary stationary weather strip engageable by the first mentionedstrip in raised position of the window member and so disposed as toprovide a clearance space between said stationary strip and windowmember, the strip carried by the window member having an upstandingprojection for clearanee space between itself ahd the window member, thestrip carried by the window member having an upstanding projection'forentering and sealing sald clearance space.
